Can you give the exact sentence in which it was used? And you have it spelled two different ways in your title and question. I suspect it should be omnipreneur...a combination of the prefix omni-, meaning "everywhere," and the word entrepreneur.

I wonder, though, is the person who was called a culinary omnipreneur only dabbling in or interested in things that are culinary...not exactly omni, then.

@JLG the article in question is about a guy who, in addition to being a chef, volunteers by cooking food for people, owns several restaurants, and gives lectures on food science at Harvard. So, he has a hand in anything having to do with the culinary arts.
